Guttation

Q.

Transpiration is least in

1. High atmospheric humidity

2. good soil moisture

3. high wind velocity

4. dry environment

Q.

Give the exact location of hydathodes.

Q. How are the minerals absorbed by plants?

Q.

Give the exact location of the following:

Hydathodes

Q.

Guttation is the process of exudation of water from plants through

1. Stomata

2. Wounds

3. Lenticels

4. Hydathodes

Q.

Guttation is:

1. Movement of soluble organic materials through plants

2. Movement of water through the apoplast

3. Evidence of root pressure

4. Negative pressure created by transpiration

Q. Do the hydathodes and water lose from hydathodes also get effected due to work of antitranspirant in a plant? If not, why not?
What is intact plant?

Q. Guttation is the result of

1. Diffusion
2. Transpiration
3. Osmosis
4. Root pressure

Q. Guttation suggests that

1. plant is transpiring rapidly
2. there is water logging around roots
3. rate of absorption is greater than rate of transpiration
4. there is absorption lag in plants
